Abstract Scope |
A cermet composite was manufactured from stainless steel (316) and silicon carbide (SiC) using a powder metallurgy process. Similar particle sizes(<20 microns) of the ceramic and steel powders were used. A wet process was selected for homogeneously mixing and binding the powders and making the pre-form for the sintering process at the sintering temperature of the steel. A synthetic polymer solution was used for powder blending and as a source of the free carbon to create multiple carbide phases in the composite during the sintering process. It was observed under x-ray analysis that multiple carbide and silicide phases were created with alloying elements in the steel, contributing to the hardness and strength of the composite manufactured. Microstructure and distribution of chemical elements were also analyzed under FESEM. Further, the crystal arrangements and formation of polycrystalline structures were studied using HRTEM. Results revealed that the mechanical property of the composite was improved. |
